docs: def removeAllEntitlements(self, appId):
          """
          This operation removes all entitlements from the portal for ArcGIS
          Pro or additional products such as Navigator for ArcGIS and revokes
          all entitlements assigned to users for the specified product. The
          portal is no longer a licensing portal for that product.
          License assignments are retained on disk. Therefore, if you decide
          to configure this portal as a licensing portal for the product
          again in the future, all licensing assignments will be available in
          the website.
  
          Parameters:
             appId - The identifier for the application for which the
              entitlements are being removed.
